Okay, did you know he calculated the size of the earth and was only off by about 100 kilometers 1500 years ago?

Has your friend told you his "proof" yet?

Here lies the reader who will never open this book. He is forever dead.

Hi bobbym,

No, I didn't know that. How did he do this? Did he have a telescope?

Hi anonimnystefy,

No. I haven't gone to school yet. But I am excited. And this person is not a normal friend of mine, he is more of a stranger. He claims to have seen and identified me an year ago. But I never saw him.

Hi;

He lived in the 4th or 5th century AD so it is unlikely that he had a telescope.

I used to know but have forgotten. Or maybe, I just thought I knew.

What did you do today?

He is a tenth grader student and I am a ninth grader. The only time we can meet each other is the break. I was busy with Nky for a while and then when I went to his room, he wasn't there.

Too general a question. Do you have something that you would like to know? If you can phrase it well then that means you understand it well enough to look at an answer.

I recently read this transcripts

It was quite ok to understand

But, When I downloaded generatingfunctionology, the book was quite difficult. Is it my lack of attention?

No, it is a difficult book. The fault is with the author. He starts by being generous, particularly the first two chapters. After that he goes into the usual mathematician mode of trying to impress his peers and baffle us.
